Someone Keeps Stealing My Letters

I just saw this site called "Just Letters" linked from a post on 43 Things.

It's a simple page with nothing but letters of the alphabet, as if they were displayed on a fridge. Up to 50 people at once move the letters around independently, creating this anonymous, chaotic environment where it's impossible to have any real control. Pointless and juvenile, yes, but worth short look and a laugh.
